Key Features & Advantages

  • Technical Advantage: Premium-grade SS304 material choice isolates active elements against galvanic corrosion, stabilizing baseline cycling data when operating under elevated voltage fields.
  • Technical Advantage: Strict dimensional replication matching 26650 industry criteria prevents localized internal mechanical clearance caps, fostering uniform electrode stack loading.
  • Technical Advantage: Complete, fully synchronized item bundling delivers casings, caps, connection pads, and gaskets in a ready-to-use configuration to maximize cleanroom assembly speed.
  • Technical Advantage: Precision engineered sealing O-rings prevent non-aqueous fluid volatilization or moisture ingress, eliminating artifact distortions during cyclic validation sweeps.

APPLICATION SCOPE: University and corporate testing laboratories developing advanced lithium-ion cathode/anode pairs, non-aqueous fluid formulation testing, structural cycle-life assessments, cylindrical cell prototyping, and portable energy storage development.
PACKAGING: Dispatched securely as a 100 sets per bag assembly kit, combining 100x stainless steel cases, 100x cell caps, 100x connection plates, and 100x internal insulating O-rings.
IMPORTANT NOTICE: These components are intended exclusively for flat-head 26650 configurations without protective circuit architecture. Store kits in a dry, ventilated cabinet away from volatile chemicals and high relative humidity. Please use proper chemical-resistant protective gear and verify your roll-groove or hydraulic crimping equipment dimensions before execution.

This kit requires storage in a dry, ventilated cabinet away from volatile chemicals and high relative humidity to prevent O-ring degradation and moisture ingress. Proper chemical-resistant protective gear must be used, and roll-groove or hydraulic crimping equipment dimensions must be verified before assembly to ensure seal integrity.

  • Storage Conditions: Store the kit in a dry, ventilated environment away from volatile chemicals and high humidity to preserve component integrity.
  • Protective Gear Requirement: Use chemical-resistant protective gear when handling the kit during assembly to avoid contamination or exposure.
  • Equipment Dimension Verification: Verify the dimensions of your roll-groove or hydraulic crimping equipment before executing the cell sealing process to prevent misalignment.
  • Moisture Sensitivity: The sealing O-rings are designed to prevent non-aqueous fluid volatilization and moisture ingress, requiring careful handling to avoid deformation.
  • Cell Configuration Constraint: These components are intended exclusively for flat-head 26650 bare cell configurations without internal protection boards.

What are the performance trade-offs of using 304 stainless steel versus alternative alloys for Atomfair 26650 battery case kits in non-aqueous electrolyte testing?

304 stainless steel (SS304) is chosen for its premium chemical resistance and high structural yield strength, which isolates active elements against galvanic corrosion and stabilizes baseline cycling data under elevated voltage fields. The 0.25 mm case thickness provides mechanical integrity while minimizing internal clearance for uniform electrode stack loading. Alternative alloys may offer different corrosion resistance or mechanical properties, but SS304 directly supports consistent electrochemical validation in non-aqueous electrolyte environments.

Can the Atomfair 26650 cylindrical battery case kits be used with 26650 cells that have built-in protection circuits?

No, these case kits are explicitly designed for standard flat-head 26650 bare cell configurations without internal protection boards or protective circuit architecture. Using cells with protection boards may cause dimensional mismatches or interfere with the sealing O-ring and cap assembly, compromising the internal pressure boundary and electrochemical test validity.

What are the critical storage and handling requirements for Atomfair 26650 battery case kits to ensure data integrity in electrochemical testing?

Store the kits in a dry, ventilated cabinet away from volatile chemicals and high relative humidity to prevent electrolyte contamination and corrosion. During assembly, use proper chemical-resistant protective gear and verify that your roll-groove or hydraulic crimping equipment dimensions match the case specifications to avoid sealing failures. These precautions eliminate artifact distortions during cyclic validation sweeps.

This 26650 battery case kit uses SS304 stainless steel with bundled components for consistent assembly, but requires compatible roll-groove or hydraulic crimping equipment and is limited to flat-head cells without protective circuit boards.

Positive

  • Premium SS304 corrosion resistance: 304 stainless steel material isolates active elements against galvanic corrosion, stabilizing baseline cycling data when operating under elevated voltage fields.
  • Complete bundled kit for rapid assembly: Includes casing, cap, conductive aluminum sheet, and sealing O-ring in a ready-to-use configuration to maximize cleanroom assembly speed and eliminate component variation during cell sealing.

Trade-offs

  • Limited to flat-head cell configurations: Components are intended exclusively for standard flat-head 26650 bare cells without internal protection boards, restricting compatibility to unprotected cell formats.
  • Requires compatible crimping equipment: Proper sealing depends on verifying roll-groove or hydraulic crimping equipment dimensions before execution, adding a processing constraint for users without such tooling.
